Ethernet/IP Data Files
The data organization shown in section 1.6 corresponds to the same mapping as
all the other communication interfaces on the Q46. All Q46 instruments provide
20 bytes of input data to the master, and the meaning of the bytes changes
slightly depending on which Q46 instrument is used.
